Conguration parameters default value Signicance and adjustments
Comfort/eco
Comfort or economy mode
Default value = Comfort
Sets the operation and interaction mode of the heat pump with
the auxiliary heat.
Comfort mode: In Heating mode. If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat will be energized to
satisfy the same heating setpoint.
Economy mode: In Heating mode. If the heat pump is not able
to satisfy the heating setpoint, the auxiliary heat will be energized
to satisfy only when the temperature has dropped 2.0 °F (1.1 °C)
below the heating setpoint. Selecting economy mode will add
a deadband between the heatpump & auxiliary heat in heating
mode. The actual temperature maintained will be lower than the
true heating setpoint to maximize the heat pump operation.
When the outdoor air temperature drops below the low balance
point, the deadband will be eliminated and the auxiliary heat will
maintain the true heating setpoint alone.
Rev. valve
Reversing valve operation
O/B
Default value = O
Heat pump reversing valve operation
O: will energize the valve in cooling operation.
B: will energize the valve in heating operation
O or B
Comp. interlock
Compressor/auxiliary interlock
Default value = Off
Sets the operation and interaction mode of the heat pump with
the auxiliary heat.
Interlock Off: In Heating mode, if the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat will be energized
at the same time as the heat pump stage. Typically applies when
the air handler heat pump coil is installed before the auxiliary
heat. (all electric systems)
Interlock On: In Heating mode, if the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat will be energized
and the heat pump will be cut off. Typically applies when the air
handler heat pump coil is installed after the auxiliary heat. (add
on systems) There is a 2 minute delay to restart the heat pump,
when the auxiliary heat is shut down
